Description

Technical Field

[0001] This utility model relates to the field of command and control cabins, and in particular to an extension mechanism for command and control cabins. Background Technology

[0002] A command module is a mobile command platform that integrates command, dispatch, and information communication functions. It typically adopts a modular design, allowing for rapid deployment and relocation. It is mainly used in emergency management, epidemic prevention and control, wartime command, and engineering emergency situations, enabling on-site commanders to promptly grasp information, coordinate resources, and make decisions.

[0003] Existing traditional command module expansion mechanisms are complex in structure and cumbersome to operate, which not only increases the cost of use but also makes later maintenance inconvenient. Moreover, many existing traditional expansion mechanisms are controlled by a single mode, such as electric motors. This means that when the drive mechanism malfunctions or other special circumstances prevent the drive mechanism from operating normally, the expansion mechanism cannot be expanded smoothly and is not practical. Therefore, a new expansion mechanism for command modules is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an extension mechanism for a command cabin, which aims to improve the existing traditional command cabin extension mechanisms, which are complex in structure and cumbersome in operation, increasing the cost of use and making later maintenance inconvenient. Moreover, some existing traditional extension mechanisms are mostly single control modes, which cannot be used normally when the drive motor fails.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an expansion mechanism for a command module, comprising a main module, with auxiliary modules installed on both the left and right sides of the main module. Multiple expansion control mechanisms are installed between the main module and the auxiliary modules. Each expansion control mechanism includes an expansion component.

A drive component is located in the middle of the housing, and a manual component is installed in the middle of the drive component. The expansion component includes an outer beam, which is fixedly connected to the bottom of the main module. An inner beam is slidably connected through the middle of the outer beam, and a tooth is provided at the bottom of the inner beam. The drive component includes a motor, and a worm gear is fixedly connected to the output end of the motor via a coupling. The worm gear is rotatably connected through the housing, and a worm wheel meshes with the upper part of the worm gear. A connecting shaft is located in the middle of the worm wheel, and the connecting shaft is rotatably connected through the housing. A gear is fixedly connected to the rear side of the connecting shaft, and the gear meshes with the inner beam.

[0007] The worm gear has a connecting groove in the middle, and a matching connecting cone is engaged inside the connecting groove. The connecting shaft and the connecting cone pass through and are slidably connected.

[0008] As a further description of the above technical solution:

[0009] The connecting cone is frustum-shaped, and multiple protrusions are fixedly connected to the outer wall of the connecting cone. The inner wall of the connecting groove is provided with a groove that matches the protrusions.

[0010] As a further description of the above technical solution:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-2This utility model provides an embodiment of an expansion mechanism for a command module, comprising a main module 1, with auxiliary modules 2 installed on both the left and right sides of the main module 1. The main module 1 and auxiliary modules 2 together form the command module. Multiple expansion control mechanisms 3 are installed between the main module 1 and the auxiliary modules 2, which are used to control the expansion and retraction of the auxiliary modules 2 on both sides of the main module 1. The expansion control mechanism 3 includes an expansion component 31, which is used to move the auxiliary modules 2. A housing 32 is installed at the front of the expansion component 31, which is used to connect various components. The housing 32 is fixedly connected to the bottom of the main module 1. A drive component 33 is provided in the middle of the housing 32, which is used to drive and control the expansion component. A manual component 34 is installed in the middle of the drive component 33, which is used to manually control the expansion component 31.

[0032] Furthermore, the bottom of the main cabin 1 is fixedly connected to a main side beam 11, which is used to connect various components. The inner beam 312 passes through and is slidably connected to the main side beam 11. The upper and lower parts of the auxiliary cabin 2 are fixedly connected to auxiliary side beams 21, which are used to connect with the inner beam 312. The inner beam 312 is fixedly connected to the auxiliary side beam 21 located at the lower part.

[0033] like Figures 3-5 As shown, the expansion assembly 31 includes an outer beam 311, which is used to connect various components. The outer beam 311 is fixedly connected to the bottom of the main cabin 1. An inner beam 312 is slidably connected through the middle of the outer beam 311, which is used to facilitate the movement of the auxiliary cabin 2. The bottom of the inner beam 312 is provided with protruding teeth, which are used to cooperate with the drive of the gear 337. The drive assembly 33 includes a motor 331, which is used to cooperate with the drive mechanism. The output end of the motor 331 is fixedly connected to a worm gear 332 through a coupling. The worm gear 332 is rotatably connected through the outer shell 32. The upper part of the worm gear 332 is meshed with a worm wheel 333, which is used to cooperate to drive the movement of the connecting cone 335. A connecting shaft 336 is provided in the middle of the worm wheel 333, which is used to connect various components. The connecting shaft 336 is rotatably connected through the outer shell 32. A gear 337 is fixedly connected to the rear side of the connecting shaft 336, which is used to cooperate to drive the inner beam 312. The gear 337 meshes with the inner beam 312.

[0034] Furthermore, a connecting groove 334 is provided in the middle of the worm gear 333, which is used to connect with the connecting cone 335. The connecting groove 334 is fitted with a matching connecting cone 335, which is used to connect with the worm gear 333 to cooperate with the motor 331 for driving or manual driving. The connecting shaft 336 passes through and slides with the connecting cone 335. The connecting cone 335 is frustoconical, with its front diameter smaller than its rear diameter. Multiple protrusions are fixedly connected to the outer wall of the connecting cone 335. The inner wall of the connecting groove 334 is provided with a groove that matches the protrusions. The groove and the protrusions cooperate with each other to connect the connecting cone 335 and the worm gear 333. Limiting strips are provided on the upper and lower sides of the front part of the outer wall of the connecting shaft 336, which are used to enable the connecting shaft 336 to drive the connecting cone 335 and the manual shaft 341.

[0035] Furthermore, the manual assembly 34 includes a manual shaft 341 for connecting various components. A connecting shaft 336 passes through and is slidably connected to the manual shaft 341. The manual shaft 341 is fixedly connected to the front side of the connecting cone 335. A control sleeve 343 is rotatably connected to the front of the outer wall of the manual shaft 341 for adjusting the position of the manual shaft 341. The control sleeve 343 is inseparable from the manual shaft 341. The control sleeve 343 passes through and is threadedly connected to the outer casing 32. A throttle 342 is fixedly connected to the front side of the manual shaft 341 for driving the manual shaft 341 to rotate.

[0036] Working principle: When using the extension mechanism, the motor 331 is turned on, which drives the worm 332 to rotate. When the worm 332 rotates, the worm wheel 333 meshing with it will also rotate. Since the middle of the worm wheel 333 is connected to the connecting cone 335 by the connecting groove 334, when the worm wheel 333 rotates, it will drive the connecting cone 335 to rotate. The connecting shaft 336, which is limited by the limiting strip of the connecting cone 335, will also rotate, thereby driving the gear 337 to rotate. When the gear 337 rotates, the inner beam 312 meshing with it will be driven to move, thereby causing the two auxiliary compartments 2 to expand and open to both sides of the main compartment 1. By controlling the worm 332 to reverse through the motor 331, the inner beam 312 can be retracted into the outer beam 311, thereby causing the auxiliary compartments 2 to retract into the main compartment 1.

[0037] If the motor 331 malfunctions and cannot open the auxiliary compartment 2 in time, the control sleeve 343 can be rotated to move the manual shaft 341 towards the gear 337. This allows the manual shaft 341 to disengage the connecting cone 335 from the connecting groove 334. Then, the throttle 342 can be rotated, causing the manual shaft 341 to rotate. At this time, the connecting shaft 336, which is connected to the manual shaft 341 via the limit bar, will also be rotated, causing the gear 337 to rotate. This allows the inner beam 312 to cooperate with the expansion of the auxiliary compartment 2. After the auxiliary compartment 2 has been expanded, the control sleeve 343 can be rotated in the opposite direction, causing the control sleeve 343 to move the manual shaft 341 away from the gear 337. At this time, the manual shaft 341 will cause the connecting cone 335 to engage in the connecting groove 334. This allows the worm gear 333 and the worm 332 to engage and restrict the connecting cone 335, thereby limiting the angle of the gear 337.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
